Quantum mechanics of a particle in an infinite square well under the influence of a time-dependent electric field is reconsidered. In some gauge, the Hamiltonian depends linearly on the momentum operator, which is symmetric but not self-adjoint when defined on a finite interval. In spite of this symmetric part, the Hamiltonian operator is shown to be self-adjoint. This follows from a theorem by Kato and Rellich which guarantees the stability of a self-adjoint operator under certain symmetric perturbations. The result, which (...) has been assumed tacitly by other authors, is important in order to establish the equivalence of different Hamiltonian operators related to each other by quantum gauge transformations.

Gleason-type theorems derive the density operator and the Born rule formalism of quantum theory from the measurement postulate, by considering additive functions which assign probabilities to measurement outcomes. Additivity is also the defining property of solutions to Cauchy’s functional equation. This observation suggests an alternative proof of the strongest known Gleason-type theorem, based on techniques used to solve functional equations.

How ought you to evaluate your options if you’re uncertain about which axiology is true? One prominent response is Expected Moral Value Maximisation, the view that under axiological uncertainty, an option is better than another if and only if it has the greater expected moral value across axiologies. EMVM raises two fundamental questions. First, there’s a question about what it should even mean. In particular, it presupposes that we can compare moral value across axiologies. So to even understand EMVM, we (...) need to explain what it is for such comparisons to hold. Second, assuming that we understand it, there’s a question about whether EMVM is true. Since there are many plausible rivals, we need an argument to defend it. In this paper, I’ll introduce a representation theorem for axiological uncertainty to answer these two questions. Roughly, the theorem shows that if all our axiologies satisfy the von Neumann–Morgenstern axioms, and if the facts about which options are better than which in light of your uncertainty also satisfy these axioms as well as a Pareto condition, then these facts have a relevantly unique expected utility representation. If I’m right, this theorem at once affords us a compelling way to understand EMVM—and specifically intertheoretic comparisons—and a systematic argument for its truth. (shrink)

Intuitively, we lack the standing to blame others in light of moral norms that we ourselves don't take seriously: if Adam is unrepentantly aggressive, say, he lacks the standing to blame Celia for her aggressiveness. But why does blame have this feature? Existing proposals try to explain this by reference to specific principles of normative ethics – e.g. to rule‐consequentialist considerations, to the wrongness of hypocritical blame, or principles of rights‐forfeiture based on this wrongness. In this paper, I suggest a (...) fundamentally different approach. Employing Timothy Williamson's idea of ‘constitutive rules’ of speech acts, I argue that this feature of blame is simply constitutive of any essentially moral form of disapproval. So if Adam had the standing to disapprove of Celia's aggressiveness in some form, necessarily, this disapproval couldn't be blame. If I'm right, this proposal thus not only answers our main question, but also sheds an interesting novel light on the very nature of blame. If we didn't have a form of disapproval with that feature, we wouldn't have our practice of holding each other to moral norms. (shrink)

The normative mechanics of promising seem complex. The strength and content of promissory obligations, and the residual duties they entail upon being violated, have various prima facie surprising features. We give an account to explain these features. Promises have a point. The point of a promise to φ is a promise-independent reason to φ for the promisee’s sake. A promise turns this reason into a duty. This explains the mechanics of promises. And it grounds a nuanced picture of immoral promises, (...) an argument against promissory bare wrongings, and a constraint on theories of why we have promissory obligations at all. (shrink)

Many people think that if you're uncertain about which moral theory is correct, you ought to maximize the expected choice-worthiness of your actions. This idea presupposes that the strengths of our moral reasons are comparable across theories – for instance, that our reasons to create new people, according to total utilitarianism, can be stronger than our reasons to benefit an existing person, according to a person-affecting view. But how can we make sense of such comparisons? In this article, I introduce (...) a constructivist account of intertheoretic comparisons. On this account, such comparisons don't hold independently of facts about morally uncertain agents. They're simply the result of an ideal deliberation in terms of certain epistemic norms about what you ought to do in light of your uncertainty. If I'm right, this account is metaphysically more parsimonious than some existing proposals, and yet has plausible and strong implications. (shrink)

Is it appropriate to blame people unequally if the only difference between them was a matter of luck? Suppose Alice would drive recklessly if she could, Belen drove recklessly but didn’t harm anyone, and Cleo drove recklessly and killed a child. Luck-advocates emphasize that in real life we do blame such agents very unequally. Luck-skeptics counter that people aren’t responsible for factors beyond their control, or beyond their quality of will. I’ll defend a somewhat reconciliatory view. I’ll concede to the (...) skeptics that these agents are equally culpable. Nonetheless, I’ll suggest with the luck-advocates that it’s fitting to blame them unequally. That’s because their culpability is unequally significant for us: Cleo’s culpability concerns us more than Belen’s, and Belen’s more than Alice’s—just like the fault of a close aggressor concerns us more than that of an aggressor far off in place and time. And it’s fitting for us to respond with more blame to faults that concern us more. Indeed, blaming people simply in proportion to their culpability manifests a form of fetishism, or problematic mere-matter-of-principle concern. So while many skeptical tenets may hold, in substance the luck-advocates are right. (shrink)

Stefan Collini challenges the common claim that universities need to show that they help to make money in order to justify getting more money.

According to an increasingly popular view among philosophers of science, both causal and non-causal explanations can be accounted for by a single theory: the counterfactual theory of explanation. A kind of non-causal explanation that has gained much attention recently but that this theory seems unable to account for are grounding explanations. Reutlinger :239-256, 2017) has argued that, despite these appearances to the contrary, such explanations are covered by his version of the counterfactual theory. His idea is supported by recent work (...) on grounding by Schaffer and Wilson who claim there to be a tight connection between grounding and counterfactual dependence. The present paper evaluates the prospects of the idea. We show that there is only a weak sense in which grounding explanations convey information about counterfactual dependencies, and that this fact cannot plausibly be taken to reveal a distinctive feature that grounding explanations share with other kinds of explanations.

Between 1918 and 1933, the masses became a decisive preoccupation of European culture, fueling modernist movements in art, literature, architecture, theater, and cinema, as well as the rise of communism and fascism and experiments in radical democracy. Spanning aesthetics, cultural studies, intellectual history, and political theory, this volume unpacks the significance of the shadow agent known as "the mass" during a critical period in European history. It follows its evolution into the preferred conceptual tool for social scientists, the ideal slogan (...) for politicians, and the chosen image for artists and writers trying to capture a society in flux and a people in upheaval. This volume is the second installment in Stefan Jonsson's epic study of the crowd and the mass in modern Europe, building on his work in _A Brief History of the Masses_, which focused on monumental artworks produced in 1789, 1889, and 1989.

Einleitung -- Charismatische Herrschaft -- Traditionale Herrschaft -- Traditionale und charismatische Herrschaft im vorrationalen Okzident: Antike -- Traditionale und charismatische Herrschaft im vorrationalen Okzident: Mittelalter -- Legale Herrschaft.

Only recently have philosophers and psychologists begun to consider empirical research methods to inform questions and debates in legal philosophy. With the field ripe for further experimental inquiry, this collection explores the most topical empirical developments and anticipates future research directions. Bringing together legal scholars, psychologists and philosophers, chapters address questions such as: Do people share a stable set of intuitions about what the law is? What are common perceptions about causation, intentionality, culpability, and are they consistent with the corresponding (...) technical legal concepts? To what extent can experimental research methods advance theoretical debates in legal philosophy about the nature of law? With fascinating implications for legal philosophy, ethics and moral psychology, Advances in Experimental Philosophy of Law sets the agenda for the emerging field of experimental jurisprudence and will be of interest to both researchers and practitioners alike.

Das Thema Staatstheorien bezieht sich auf eines der wichtigsten Gebiete der staatsbürgerlichen Erziehung und damit der stabilen freiheitlich-demokratischen Grundordnung überhaupt. Staatstheo-rien sind in verschiedenen Ausprägungen vorhanden und insofern sind Selektionskriterien und Begründungen erforderlich. Die Staats-theorien der Aufklärung werden zu Recht als maßgeblicher Ein-flussfaktor der heutigen westlichen Demokratieformen gesehen. Innerhalb der Aufklärung gibt es eine Kanonbildung der Vertrags- und Staatstheorien: Hobbes, Locke, Montesquieu und Rousseau besitzen seit geraumer Zeit einen festen Platz darin. Zwischen Demokratie und politischer Bildung herrscht ein enger und (...) systematischer Zusammenhang. Demokratie bedeutet dabei gleichzeitig Lebens-, Gesellschafts- und Herrschaftsform. Nicht zu-letzt aus dieser fundamentalen und umfassenden Bedeutung für das Zusammenleben in unserer Gesellschaft rechtfertigt sich die Relevanz des Themas Staatstheorien als Gegenstand einer wissen-schaftlichen Abhandlung. Den Leserinnen und Lesern soll die exorbitante Relevanz des The-mas für unser heutiges gesellschaftspolitisches Zusammenleben vor Augen geführt werden. (shrink)

Stefan Jonsson uses three monumental works of art to build a provocative history of popular revolt: Jacques-Louis David's _The Tennis Court Oath_ (1791), James Ensor's _Christ's Entry into Brussels in 1889_ (1888), and Alfredo Jaar's _They Loved It So Much, the Revolution_ (1989). Addressing, respectively, the French Revolution of 1789, Belgium's proletarian messianism in the 1880s, and the worldwide rebellions and revolutions of 1968, these canonical images not only depict an alternative view of history but offer a new understanding (...) of the relationship between art and politics and the revolutionary nature of true democracy. Drawing on examples from literature, politics, philosophy, and other works of art, Jonsson carefully constructs his portrait, revealing surprising parallels between the political representation of "the people" in government and their aesthetic representation in painting. Both essentially "frame" the people, Jonsson argues, defining them as elites or masses, responsible citizens or angry mobs. Yet in the aesthetic fantasies of David, Ensor, and Jaar, Jonsson finds a different understanding of democracy-one in which human collectives break the frame and enter the picture. Connecting the achievements and failures of past revolutions to current political issues, Jonsson then situates our present moment in a long historical drama of popular unrest, making his book both a cultural history and a contemporary discussion about the fate of democracy in our globalized world.

The topic of this thesis is axiological uncertainty – the question of how you should evaluate your options if you are uncertain about which axiology is true. As an answer, I defend Expected Value Maximisation (EVM), the view that one option is better than another if and only if it has the greater expected value across axiologies. More precisely, I explore the axiomatic foundations of this view. I employ results from state-dependent utility theory, extend them in various ways and interpret (...) them accordingly, and thus provide axiomatisations of EVM as a theory of axiological uncertainty.

Examines widespread myths about transhumanism and explores the most pressing ethical issues in the debate over technologically assisted human enhancement.

Explainable artificial intelligence (XAI) aims to help people understand black box algorithms, particularly of their outputs. But what are these explanations and when is one explanation better than another? The manipulationist definition of explanation from the philosophy of science offers good answers to these questions, holding that an explanation consists of a generalization that shows what happens in counterfactual cases. Furthermore, when it comes to explanatory depth this account holds that a generalization that has more abstract variables, is broader in (...) scope and/or more accurate is better. By applying these definitions and contrasting them with alternative definitions in the XAI literature I hope to help clarify what a good explanation is for AI. (shrink)

Artificial Intelligence (AI) is increasingly adopted in society, creating numerous opportunities but at the same time posing ethical challenges. Many of these are familiar, such as issues of fairness, responsibility and privacy, but are presented in a new and challenging guise due to our limited ability to steer and predict the outputs of AI systems. This chapter first introduces these ethical challenges, stressing that overviews of values are a good starting point but frequently fail to suffice due to the context (...) sensitivity of ethical challenges. Frequently, additional (ethical) values emerge for specific applications, as e.g. challenges with fraud detection are very different from those around language technologies. Second, methods to tackle these challenges are discussed. Main ethical theories (virtue ethics, consequentialism, and deontology) are shown to provide a starting point, but often lack the details needed for actionable AI Ethics. Instead, mid-level philosophical theories coupled to design-approaches such as Design for Values, together with interdisciplinary working methods, offer the best way forwards. The chapter aims to show how these approaches can lead to an ethics of AI that is actionable and that can be proactively integrated in the design of AI systems. (shrink)

This study defends the legitimacy of the Enlightenment project by way of its different realizations in the philosophies of Immanuel Kant and Friedrich Heinrich Jacobi. Today, Enlightenment as a cosmopolitan project with a global claim is often considered synonymous with Western chauvinism. The assertion of a universally binding reason is all too obviously inconsistent with the much-cited recognition of cultural differences. In contrast, it is the conviction brought forward in this book that an adequately understood Enlightenment is an unconditional right (...) of every person taking an active interest in a self-determined way of life. Only the realization of this conception of Enlightenment can provide the required space for the reciprocal recognition of human differences to freely unfold. (shrink)

This imaginative and unusual book explores the moral sensibilities and cultural assumptions that were at the heart of political debate in Victorian and early twentieth-century Britain. It focuses on the role of intellectuals as public moralists and suggests ways in which their more formal political theory rested upon habits of response and evaluation that were deeply embedded in wider social attitudes and aesthetic judgments. Collini examines the characteristic idioms and strategies of argument employed in periodical and polemical writing, and reconstructs (...) the sense of identity and of relation to an audience exhibited by social critics from John Stuart Mill and Matthew Arnold to J.M. Keynes and F.R. Leavis. (shrink)

Die Begegnung von Buddhismus und Christentum fordert ein verwandeltes Selbstverständnis philosophischen Denkens. Der japanische Philosoph Keiji Nishitani sieht in der existenziellen Radikalisierung der Frage «Was ist Religion?» bis zum buddhistischen Standpunkt der Leere die Möglichkeit der Überwindung des Nihilismus. Seine Geschichtsinterpretation öffnet in dieser Arbeit den Zugang zu Nietzsches Leib-Denken in seinem Zarathustra. In diesem Rahmen versucht der Verfasser, mit einer Methodenvielfalt und in Auseinandersetzung mit wichtigen abendländischen Denkern die Fraglichkeit jener Frage an ihre Grenze zu treiben.

Die vorliegende Arbeit hat den Leibnizschen metaphysischen Optimismus und einige der weniger bekannten Stationen und Zuge der Rezeption der "Essais de Theodicee" und des Theorems von der besten Welt im deutschen 18. Jahrhundert zum Gegenstand. Sie erhebt nicht den Anspruch, eine auch nur annahernd vollstandige Darstellung des Verlaufes der Debatte um die "beste Welt" zu geben. Angesichts der Fulle der zeitgenossischen Einlassungen und Ausserungen zum Thema war eine Auswahl bestimmter Rezeptionsmomente vorzunehmen. Auf die Prozesse der Verwandlung einer strikt metaphysischen Theodizee (...) hin zu einem populareren, dafur aber auch anfechtbareren Optimismus will diese Arbeit ebenso hinweisen wie auf den Umstand, dass nicht erst die Kantische Schrift "Uber das Misslingen aller philosophischen Versuche in der Theodizee" von 1791 die (philosophische) Problematik der Lehre von der besten Welt dingfest macht.

In contemporary theories of language it is common to appeal to propositions as expressed by utterances of sentences. The aim of this paper is to question this idea, for as I argue, the relationship between sentences and propositions cannot be worked out in any rewarding way.

The paradox of predictability refers to situations in which, even in a deterministic universe, a correct prediction of a future action is seemingly impossible because the agent whose action is predicted is determined to act counterpredictively. In a recent contribution to this journal, Victor Gijsbers provides an example of the paradox in which the undecidability of the situation plays an essential role and claims, additionally, that this undecidability is at the root of all examples of the paradox. This paper argues, (...) first, that the latter claim is not correct because there are clear examples of the paradox in which the situation remains fully decidable. The paper argues, secondly, that, because of its reliance on rather artificial conditions and in contrast with examples referring to the physical nature of the predictor, the example presented by Gijsbers, though technically correct, has little relevance for our understanding of the role of (counter-)predictability in the context of human interactions.

There are several conceptions of man in the history of philosophy. However, two considerable tendencies are recurring throughout modern history. A human being can be perceived as a complex mechanism or as a living organism. The response to the query has essential consequences in different areas. The article aims to provide a view of humankind that builds upon an organic conception of life, nature, and human beings, especially as elaborated by A. N. Whitehead and some of his followers. The article (...) also briefly examines the emergence and development of a mechanistic view. The historical overview exposes the close relationship between the worldview of a given era and the understanding of man. Finally, the article argues that the organic conceptions of life developed in the first half of the 20th century provide an essential alternative to mechanistic views and could help us to deal with several problems we are currently encountering.

Metatheoretical codifications of the sociological writings of George H. Mead, Jose Ortega y Gasset, and Alfred Schutz highlight the importance of the idea of life and of a commitment to a realist perspective. The authors turn common concern with the life concept in three directions: evolutionary emergence, historical rationality, and phenomenological analysis. In spite of differences, these directions share an empirically grounded starting point in the situated individual and its environment, and end with suggestions for a universalist rationality. Preliminary metatheoretical (...) principles from these authors offer a start toward a vital realist sociology fitted to the universal conditions of social life. (shrink)

More than 50 years ago, Bongard introduced 100 visual concept learning problems as a challenge for artificial vision systems. These problems are now known as Bongard problems. Although they are well known in cognitive science and artificial intelligence, only very little progress has been made toward building systems that can solve a substantial subset of them. In the system presented here, visual features are extracted through image processing and then translated into a symbolic visual vocabulary. We introduce a formal language (...) that allows representing compositional visual concepts based on this vocabulary. Using this language and Bayesian inference, concepts can be induced from the examples that are provided in each problem. We find a reasonable agreement between the concepts with high posterior probability and the solutions formulated by Bongard himself for a subset of 35 problems. While this approach is far from solving Bongard problems like humans, it does considerably better than previous approaches. We discuss the issues we encountered while developing this system and their continuing relevance for understanding visual cognition. For instance, contrary to other concept learning problems, the examples are not random in Bongard problems; instead they are carefully chosen to ensure that the concept can be induced, and we found it helpful to take the resulting pragmatic constraints into account.

Die Frage nach Sinn ist eine bleibend existentielle Frage des Menschen. Sie wird dringend aktuell in einer Zeit zunehmender Säkularisierung und Multioptionalität. Eine Theologie, die die Gesellschft prägen will, muss hierzu eine Antwort aus der Mitte des christlichen Glaubens geben können. Stefan Laurs stellt sich dieser Herausforderung. In Auseinandersetzung mit Charles Taylor und Walter Kasper analysiert er den neuzeitlichen Säkularisierungsprozess und widmet sich insbesondere der damit verbundenen Frage des Menschen nach Sinn und Erfüllung. Dabei wird ersichtlich, dass die Sinnfrage (...) aus theologischer Perspektive in der Gottesfrage zur Darstellung kommt. Nur in Gott, der Liebe ist, findet der Mensch den universalen Sinn un die Erfüllung seines Lebens. (shrink)

The remodeling of biological membranes is crucial for a vast number of cellular activities and is an inherently multiscale process in both time and space. Seminal work has provided important insights into nanometer‐scale membrane deformations, and highlighted the remarkable variation and complexity in the underlying molecular machineries and mechanisms. However, how membranes are remodeled at the micron‐scale, particularly in vivo, remains poorly understood. Here, we discuss how using regulated exocytosis of large (1.5–2.0 μm) membrane‐bound secretory granules in the salivary gland (...) of live mice as a model system, has provided evidence for the importance of the actomyosin cytoskeleton in micron‐scale membrane remodeling in physiological conditions. We highlight some of these advances, and present mechanistic hypotheses for how the various biochemical and biophysical properties of distinct actomyosin networks may drive this process. (shrink)
